Abstract

A novel diimine Cu(I) complex [Cu(ABPQ)(DPEphos)]BF₄ [ABPQ and DPEphos are acenaphtho[1,2-b]bipyrido[2,3-h;3,2-f]quinoxaline and bis(2-(diphenylphosphanyl)phenyl) ether, respectively] is synthesized, and its photophysical properties are experimentally and theoretically characterized. The emission bands centered at ca. 400/470 and 550 nm of [Cu(ABPQ)(DPEphos)]BF₄ are attributed to the ligand-centered π → π* transition and the metal-to-ligand charge transfer dπ(Cu) → π*(N-N) transition, respectively. The luminescence quantum yield of [Cu(ABPQ)(DPEphos)]BF₄ in CHCl₃ is found to be about five times higher than that of [Cu(Phen)(DPEphos)]BF₄.
